Air Purifier Filter Lifespan in Wildfire Areas — Replacement Calculator
Wildfire smoke contains fine particulate matter (PM2.5) that clogs HEPA filters 2-3x faster than normal air pollution. If you live in a wildfire-prone area (California, Oregon, Washington, British Columbia), you may need to replace filters during and after smoke events, even if the filter isn't technically expired.
This calculator helps you budget for the increased filter replacement frequency that comes with living in wildfire territory.
